Firstly, awesome tool! Have heard of these node based texture generators but never tried them and was amazed at what this can do!

Really glad u like it :D

I'm creating textures for a mobile Unity project and one thing I was after was the ability to output a single texture so it will be fast for mobiles (PBR's can be a bit of a drain). Would be great to have this as an export options. For now I wrote a scene in Unity to do it, which has two angle controls on a directional light and its brightness and then it exports an image. Bit fiddly but can take your output and "bake" it down.

I'm sorry but I have no plans to add this feature. If I do, it would be super low priority and not any time soon.

The second wish is for support for alpha. Not sure if this is a common thing for such tools but if I want to create a fence or some such then alpha would be really useful.

There's alpha support, it was just broken. Thanks for bringing this to my attention. I fixed the issue. New builds with this fix will be in  the discord's #build channel.
